Plants  Collected  by  Dr.  Geo.  F.  Gaumer  in  1895-96,  Dr.  Arthur  Schott  in  1864- 
66,  and  Mr.  Witmer  Stone  in  1890.

Theodor  Loesener ;  and  additional  notes  and  species  by  the  author. 


Third  Contribution  to  the  Coastal  and  Plain  Flora  of 

Yucatan. 

CHARLES  F.  MILLSPAUGH,  M.D. 


Since  the  issue  of  the  second  of  these  contributions,  this  Museum 
has  been  so  fortunate  as  to  secure  from  the  widow  of  the  late  Dr. 
Arthur  Schott,  his  entire  herbarium,  which  includes  about  nine  hun- 
dred Yucatan  plants  collected  by  him  in  1864-66  while  engaged  by 
the  Mexican  Government  to  make  a  geologic  survey  of  the  Peninsula. 
This  collection  is  of  great  importance,  it  being  the  first  really  com- 
prehensive attempt  to  collect  the  flora  of  this  region.  It  is,  however, 
to  be  regretted  that  Dr.  Schott's  idea  of  numeration  should  have  been 
that  of  numbering  his  collections  at  home,  instead  of  in  the  field,  and 
attempting  to  group  his  species  of  whatever  habitat  under  certain 
arbitrary  numbers,  before  such  species  had  been  positively  ascertained. 
This  will  cause  conflict  between  many  of  the  numbers  published  in 
these  contributions  and  those  in  the  herbaria  of  the  National  Museum 
and  Kew,  where  part  sets  of  these  plants  have  been  previously 
deposited  by  him.  A  majority  of  his  plants  are  included  in  this  con- 
tribution. 

In  1890  an  expedition  was  sent  into  Mexico  under  the  auspices 
of  the  Academy  of  Natural  Sciences  of  Philadelphia,  and  in  charge 
of  Prof.  Angelo  Heilprin.  The  work  extended  from  the  Orizaba 
region  to  the  Peninsula  of  Yucatan,  where  Mr.  Witmer  Stone,  the 
Ornithologist  of  the  party,  incidentally  collected  about  three  hundred 
plants.  These  were  approximately  determined  by  the  late  Mr.  J.  H. 
Redfield  and  distributed,  as  about  ninety-five  species,  in  the  herb- 
arium of  the  Academy,  whence  they  have  been  kindly  reassembled 
by  Mr.  Stewardson  Brown,  and  communicated  to  me  for  study  by 
the  Academy.  These  species,  so  far  as  determined  at  this  time,  are 
also  included  here. 

Even  a  limited  opportunity  to  examine  the  collections  at  the 
herbarium  of  Columbia  University  convinces  me  that  the  collection 
made  by  the  Hon.  E.  P.  Johnson  in  Yucatan  and  Tabasco,  in  1848,

is  of  considerably  greater  proportions  than  Professor  Helmsley 
reports  in  the  botanical  volumes  of  the  Biologia  Centrali-Americana. 
Only  a  patient  overhauling  of  the  whole  herbarium  can  definitely 
settle  the  question  of  the  species  in  this  collection.  A  few  genera  in 
Leguminosae  revealed  several  plants  which  I  have  incorporated  in  the 
following  list. 

Dr.  Geo.  F.  Gaumer  has  continued  his  collections  during  the 
past  year.  These,  so  far  as  determined,  form  the  basis  of  this  con- 
tribution, and  appear  in  the  text  in  parenthesized  numerals  in  the 
body  type — the  numbers  of  other  collectors  being  in  italics. 

To  the  above  collections  are  added,  in  the  following  list,  a  few 
hitherto  unclassified  numbers  collected  by  the  author  in  1887,  and  in 
1895  while  a  member  of  the  Allison  V.  Armour  expedition,  and  the 
remaining  numbers  of  Sr.  Porifirio  Valdez'  century  of  "Medicinal 
Plants"  collected  in  1895.  As  heretofore,  the  species  appearing  in 
black-face  type  are  new  to  the  region  covered  by  these  publi- 
cations. 

Those  specialists  who  have  kindly  contributed  to  the  knowledge 
of  the  species,  are  credited  under  the  orders  they  have  worked.

The  usual  form  of  the  species  with  cuneate-lanceolate  irregularly 
serrate  leaves,  smooth  capsules,  and  virgate  sparsely  leafy 
branchlets. 

Merida,  Sept.  30,  1865  (Schott,  960).  "This  plant  is  used  for 
washing  clothing." 

Euphorbia  heterophylla  forma. 

"  Herb  4  feet  high,  common  at  Buena  Vista  Xbac,  September  " 
(1109). 

A  peculiar  form  in  which  the  stem  leaves  are  broadly  lanceo- 
late, entire  or  minutely  and  distantly  dentate-serrate,  strigosely 
short-hairy  beneath;  while  those  of  the  extended  virgate  branch- 
lets  are  elongated-linear,  quite  resembling  those  of  var.  gramtni- 
folia  Engelm.  This  form,  but  with  some  of  the  lower  leaves, 
panduriform  (E.  heterophylla  cyathophora  (Jacq.)  Boiss),  was  col- 
lected in  1879  at  Fountaindale,  Oregon,  and  Byron,  Illinois, 
U.  S.  A.,  by  the  late  Mr.  M.  S.  Bebb.

Merida,  1865  (Schott,  961}.  This  form  of  a  very  varied  sub- 
species is  completely  vested  with  cyathiform  leaves,  from  those 
of  the  base  to  the  floral  at  the  apex.  Generally  the  basal  leaves 
only  distinguish  the  variety,  the  apical  being  either  lanceolate  or 
linear.  The  nearest  counterpart  of  this  plant  was  grown  by.  Dr. 
Geo.  Engelmann  from  seed  sent  him  from  Texas.  (See  sp.  in
